Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Question

**Understanding the Code Example**

In this code snippet, the task is to convert a given string "Mary Smith" into lowercase using C++. Let's break it down:

```cpp
string name = "Mary Smith";
for (unsigned int i = 0; i < name.length(); i++)
{
if (isalpha(name[i]))
/* insert code here */
}

cout << name << endl;
```

**Explanation:**

- A `string` variable `name` is initialized with the value "Mary Smith".
- A `for` loop is set to iterate over each character of the string `name`, using `i` as the index. The loop runs from 0 to `name.length() - 1`.
- The `isalpha` function checks if the character at the current index `i` is an alphabetic character.
- The exact operation to convert the `name` to lowercase is missing and needs to be inserted where `/* insert code here */` is indicated.
- The program then outputs the modified `name`.

**Task:**

The question asks: "What line of code should you put in place of `/* insert code here */` so that it prints `mary smith` (all letters in lower case)?"

**Solution:**

You need to include the following line inside the `if` statement:

```cpp
name[i] = tolower(name[i]);
```

This line changes the current character to its lowercase equivalent using the `tolower` function, ensuring that the entire string is printed as "mary smith" in lowercase.

In other words, it will return the Boolean value True if it has one, and False if it does not. After compiling the above cell, you should be able to compile the following cell and obtain the desired outputs. print (has perfect({"A" : ["B", "C"], "B" : ["A", "D"], "C" : ["A", "D"], "D" : ["B", "C"]}), has perfect ( {"A" : ["B"], "B" : ["A", "D", "E"], "C" : ["E"], "D":["B"], "E": ["B","C","F"], "F":["E"]})) This should return True False Python Python
